Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939140, here are decompositions:

19 + 939121 = 939140
31 + 939109 = 939140
79 + 939061 = 939140
151 + 938989 = 939140
157 + 938983 = 939140
193 + 938947 = 939140
271 + 938869 = 939140
283 + 938857 = 939140

Showing the first eight; more decompositions exist.
